To all whom 1lb may concern:

Be it knownthat I, HERBERT i POWELL, of' Clinton, in the county of Oneida ving is a full, clear,

ings are and State of New York, have invented certain new and useful Improvements in Muffiers; and I do hereby declare that the followand exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference. marked thereon, which form part o this specification.

'The object of my inventionis to rovile a strong and efficient muier for exp osiveeenes and. one which is economically manu.- actured, is well adapted to withstand the detrimental effects of expansion and contrae-tion, and is free from resonant troubles.

Figure l of the drawings shows a side ele vation of a muffler of my improved construction. Fig. 'shows a'longitudinal section of the same. Fig. 3 is a partial end view as seen from the left-hand endof Fig. I. Fig. 4 is a artial view of one of the sections from which the mufiier is constructed.

Referrin to the reference-letters in a more particular escription, a indicates one of the several similar sections from which the mufiler is constructed, said sections being draan metal cups of a truncated-cone form, having the bottoni b of each section in the smaller or reduced end and the open end of a diameter to receive the reduced end of the next adjacen't section, while the bottoms of the sec.- ticiis are spaced apart, thereby affording7 the chambers c c, Sec. The several sections are .provided with numerous holes or openings, as d, through the bottoms b and these openi'eferably arranged in a circle adjacent to tiie outer shell 'of the section. In the first section there is provided a head e, havinov an inlet-opening f, preferably screw-threa ed, as shown, to receive the end of a ipe. The several sections are held together y a pair of rods g gc extending longitudinally through the length o the mufller,v throng the head c, and the bottom b of the final sectoms of the several main sections.

s l l SPENCER indicated b the next adjacent section and the cessive chambers c until it is finally allowed 6o tion. The openings in the final section b are eter than t e openings inthe eads or bot- By tens'on on the rods g g the base of each section is rmly wedged into the open end of tion is very stiff' and substantial. The discharge from the gas or explosive en e is received through theinlet-opening and distributed and discharged into the several sucto escapeat the openings h. The dischar e from gas and explosive engines 'is usually quite ot and has a very detrimental effect u vn the muffler. The fact that the'sections o this mufiier' can be readil from drawn steel and that t e bottom or closed end of each section stands practicall in the mouth or open end of the section wit which it engages, the detrimental effect of expansion and contraction is reduced to the 7o minimum and resonant troubles due to vibration of sections or parts is reduced to a mniinum or entirely eliminated.

Itis evident that some changes and variations in shown and described may be made without departin from the spirit of m invention.

, 'hat claim as new, and esire to secure Vby Letters Patent, is-

'A muilier for explosive-engines consisting 8c of a series of similar cup-shaped tapering sec` f tions partially nested to provide a series of undivided \and unobstructed expansion-chambers c, c, the bottom of each section being perforated with numerous holes for the diffusion 85 and passage of gases directly from one chamber to the other, and a head with an inletopenin provided in thel first section, substantia ly as set forth.

In witness whereof I have affixed my si 9o nature, in presence of two witnesses, this 30t day of December, 1905.

i HERBERT SPENCER POWELL.
